Monday, September 17th: Families of Linear Functions
Functions in the form f(x) = mx + b are LINEAR. m is the slope of the line. b is the y-intercept of the line. These are the parameters for a line. They determine the shape of the graph. Classwork: Problem 101 on page 39 Homework: 1.2.3 #105, 106, 108, 110 due Wednesay
Wednesday-Friday, September 12th-14th: Summary Statements
Each group graphed a new function and found the domain and range. (lowest and highest values of x) We then wrote SUMMARY STATEMENTS to go with each graph. (See examples on page 34 problem 81) Homework: 1.2.2. # 84-87, 90, 91
Tuesday, September 11th: Points of Intersection
VIDEO NOTES: Points of Intersection Video You can find points of intersection on any of the representations for functions.
Graphs: Look for the points where the two graphs cross each other. Use TRACE on the calculator to estimate the points (x,y).
Tables: Look for an x-value that gives the same y-value for both functions.
Equations: Set the equations equal to one another and solve for x. Plug in x to solve for y.
Homework: 1.1.4 #47-53 due Thursday 9/13 Monday, September 10th: Domain and Range
Domain: The list of all x-values that can be put into a function. (left/right)
Range: The list of all y-values that can come out of a function. (bottom/top)
ASK: Are there any holes or breaks in the graph?

"f" is the name of the equation, x is the input, and y is the output.
Example: If f(x) = 2x - 3 f(4) = 2(4) - 3 =8 - 3 = 5 4 is the input (x); 5 is the output (y or f(x)) Homwork: 1.1.1 Worksheet #4-9 due Friday 9/7 see www.cpm.org for the problems under HOMEWORK HELP Wednesday, September 5th: Team Problem Solving

Thursday, September 6th: Function Notation
f(x) = y is notation that names an equation, input and output. "f" is the name of the equation, x is the input, and y is the output.
Example: If f(x) = 2x - 3
f(4) = 2(4) - 3
=8 - 3
= 5
4 is the input (x); 5 is the output (y or f(x))
